As you drive into deceptively developed Hilo, county seat of the island, the driver in your family will breathe a deep sigh of relief. If your group "foolishly" made a day trip of it from the Kona or Kohala Districts, the odometer now tells you that you've driven well over 100 miles from the western town of Kailua-Kona to Hilo on the eastern coast. The big difference as you will discover during your time here is that while Kailua-Kona is located on the dry leeward side, Hilo is located on the lush windward side of the Big Island. Hilo's townsfolk may have bright and sunny dispositions, but an average annual rainfall of over 120 inches makes Hilo the wettest city on record in the United States.
